Product Description

WJ-1 is a compact and lightweight Load Haul Dump (LHD) for narrow vein mining, easy 
to operate and maintain, and it features an operator compartment that is located in the 
rear frame of the machine to ensure increased operator safety. The WJ-1 is full of 
features to help mines maximize tons and minimize extraction costs. It has been 
engineered to optimize machine width, length and turning radius, enabling operation in 
narrower tunnels for less dilution and lower operational costs.

Main Features 
<< Structure 
◆
The frames are articulated with 38° steering angle. 
◆
Ergonomics Canopy with side seat to provide broad operation vision. 
<< Operation Comfort & Safety 
◆
4 wheels driving & braking. 
◆
Combination design of parking brake & working brake ensures good braking 
performance. Braking model is SAHR(spring applied, hydraulic release). 
◆
Axles are equipped differentials. The front is NO-SPIN while the rear is standard.◆
Hydraulic Joystick control to reduce the labor intensity of the driver. 
<< Early Warning & Maintenance 
◆
Automatic alarm system for oil temperature, oil pressure and electrical system. 
<< Energy-saving & Environment Friendly 
◆
Germany DEUTZ engine, powerful & low-consumption. 
◆
Hydrostatic transmission system, high efficiency and low energy consumption. 
◆
Catalytic purifier with silencer, which greatly reduces air and noise pollution in working 
tunnel.
